Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, flashlight, and safety gloves.
Ensure the vehicle is parked on a level surface, with the engine off and cooled down.

2. Check Engine Oil

Locate the oil dipstick, remove it, and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
- If low, top off with the recommended oil type (consult owner's manual for specifications).
- If the oil is burnt (dark and has a burnt smell), consider an oil change.

3. Inspect the Brake System

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear or signs of overheating.
- Replace pads if they are below the minimum thickness or if the rotor is warped.

4. Examine Electrical Components

Visually inspect wiring harnesses and connectors for signs of melting or chafing.
Use a multimeter to check for continuity in suspect wiring.
- Repair or replace any damaged wires or connectors.

5. Test Drive and Monitor

Lower the vehicle and take it for a test drive, monitoring for any return of the burning smell or warning lights.
Pay attention to braking performance and engine behavior during the drive.
